Antitheft device for electric bicycle and electric bicycle

Abstract

The invention provides an antitheft device for an electric bicycle and the electric bicycle. The antitheft device for the electric bicycle comprises a power supply and a voltage stabilizing circuit. The power supply is used for providing power for the electric bicycle and the antitheft device. The voltage stabilizing circuit is used for making the power supply output voltage stably. The antitheft device for the electric bicycle further comprises a password circuit and an alarm unit. The password circuit is connected with the voltage stabilizing circuit, the alarm unit is connected with the password circuit, the password circuit is used for setting an antitheft password and a power switch password, and the alarm unit is used for starting on-site alarming and informing a vehicle owner of the stealing situation when the electric bicycle is stolen. The antitheft device for the electric bicycle not only can give a loud alarm on the site to frighten a thief, but also can inform the vehicle owner of the stealing situation through telephone dialing, and thus a better alarm effect is achieved. The shortcomings that an ordinary electric bicycle is easily subject to the damage by the thief when a key power switch or an ordinary power switch is adopted, so that the whole bicycle is subject to outage and does not work; and a vehicle owner using a wireless remote switch must take the wireless remote switch with himself, so that inconvenience in use is caused are overcome.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an electric bicycle anti-theft device and an electric bicycle. Background technique [0002] Electric bicycles are usually provided with anti-theft devices. The traditional anti-theft device includes an alarm device, which is installed on the electric bicycle. When the electric bicycle is stolen, the alarm device sends an alarm sound to remind the owner that the car is stolen. [0003] The alarm principle of the alarm device is usually as follows: first, the electric bicycle is turned on the anti-theft mode, when the electric bicycle is moved or pushed away, the alarm device is triggered, thereby sending out an alarm signal, such as a sound signal and a light signal. [0004] The existing electric bicycle alarms control the working state of the whole machine through the key power switch or ordinary power switch, wireless remote control switch. In actual use, the key power ...

AI Technical Summary

Problems solved by technology

[0004] The existing electric bicycle alarms control the working state of the whole machine through the key power switch or ordinary power switch, wireless remote control switch. In actual use, the key power switch or ordinary power switch is easily damaged by thieves and the whole vehicle is powered off. In this case, when the car is stolen, the alarm device cannot be triggered to send an alarm signal; when using the wireless remote control switch, it is inconvenient to use because the owner must carry the wireless remote control switch with him.

[0005] In addition, the alarm device can only send out an alarm signal for on-site alarm. If the owner is not on the scene, he cannot know the situation of the car being stolen. Therefore, it is impossible to take corresponding anti-theft measures in time when the car is stolen.
